VALVE.

Specification of Letters Patent. Application filed October 25, 1902'Serial No. 128,838.

Patented Aug. 7, 1906.

To all whmn it may concern:

Be it known that I, JAMEs F. McELnoY, a citizen of the United States ofAmerica, and a resident of Albany, in the county of Albany and State ofNew York, have invented certain new and useful Improvements in Valves,of which the following is a specification.

My invention relates to improvements in valves; and the object of. myinvention is to provide a valve especially adapted for use as an endvalve in a railway-car-heating equipment so constructed that the valvemay be opened by the operation of a crank or handle and when opened orclosed will remain in its position in spite of the jar attendant uponthe movement of the car to which it is at: tached. I attain this objectby means of the mechanism illustrated in the accompanying drawings, inwhich Figure 1 is a section of anend valve. Fig. 2 is a section alongthe linesX X on Fig. 1. Fig. 3 is a perspective view of the spindle S.

Similar letters refer to similar parts throughout the several views.

The fitting A is provided with a port B, adapted to connect with atrain-pipe (not shown) and with a port 0, adapted to connect with a hoseto conduct the fluid to the adjoining car, said hose not shown. Thevalve D is arranged to close the port 0 and is suitably connected withthe spindle S by means of a hinge E, secured at one end to the valve D,having its other end provided with an eye through which the spindlepasses. Arranged adjacent to and projecting from the periphery of saideye are two shoulders F and G on opposite sides,respectively, of saideye. The spindle S passes intothe fitting A and has a handle S at oneend thereof and a bearing in the fitting at the opposite end. On thespindle S, I preferably arrange a curved portion or hood T, partlyenveloping the spindle, separated therefrom sufficiently to allow theeye on the hingeEto be placed on the spindle under the hood. The lateraledges of the hood T are adapted to engage with the shoulders F and G,respectively, on the hinge E. The location of the hood on the spindle isso adjusted in reference to the shoulders F and G on the hinge E that aquarter movement of the handle S will be made before the hinge E ismoved. For this reason when the valve is closed, as shown by full linesin Fig. 1, the handle S will be raised to a vertical position and thehood will come in contact with the shoulder G. A further movement willlift the valve from its seat. When the handle is brought to the positionshown by the dotted lines in Fig. 1, the valve will be opened to thefull limit and will be held in position by the weight of the handle. Bythis arrangement, since the valve is not opened until the handle haspassed the vertical position, there is no danger of the valve becomingunintentionally closed by the vibration or the ar of the car, as everymovement will tend to cause the handle to assume a horizontal positionand will therefore open the valve and-hold it open. In closing the valvethe reverse operation is employed. The handle will be moved to thevertical position before it will engage with the shoulder F. A furthermovement will tend to close the valve and to hold it in a closedposition.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A fitting provided with ports; a valve arranged to close one of saidports; a hinge connected with said valve; a spindle upon which saidhinge is mounted; a projection on said spindle adapted to engage withsaid hinge after a partial revolution of said spindle; a handle on saidspindle; said handle so adjusted that when the handle is substantiallyhorizontal and extending from one side of said spindle the valve will beheld closed by the weight of the handle, and when said handle is in asubstantially horizontal position extending from the other side of saidspindle said valve will be held open by the weight of said handle.

2. A fittingprovided with ports; a valve arranged to close one of saidports; a spindle; a handle on said spindle; a hood secured to saidspindle; a hinge connected with said valve; said valve opened and closedby the engagement of said hood with said hinge after apartial revolutionof said spindle; said handle when occupying a substantially horizontalpositiofii lgliltiending frcim 011w scilde 05 said spin e o sai Va ve cose an I when said handle gecupies a substantially 1 JAMES MOELROY'horizontal position extending from the op- Witnesses:
